Response of the eye to a flash of light.

Abstract

ABSTRACT An earlier paper has dealt with the mechanisms subserving bright and dark adaptation. Additional mechanisms must be postulated to deal with the response to a flash of light. The characteristics of these mechanisms have been derived from a study of such phenomena as the Blondel‐Rey effect, Bloch's law, alpha and beta adaptation and the Broca‐Sulzer effect. Consideration is also given to the measured responses of limulus photoreceptors and monkey cones to flashes of light.
